Subject: [PATCH v2 00/27] context_tracking, rcu: Spring cleaning renaming
Date: Tue, 30 Apr 2024 11:17:04 +0200 [thread overview]
Message-ID: <20240430091740.1826862-1-vschneid@redhat.com> (raw)
Hi folks,
This is v2 of [1], where I've now gone through the rabbit hole of renaming /just
a few/ more things.
I've done one patch per symbol for my own sanity, a lot of these probably
deserve to be squashed together (e.g. all of the nmi_nesting into one).
All patches are pure renaming, with the exception of:
- patch 14/27, which also lifts a negation out of a function and straps it to its
callsites.
- patch 27/27, which renames a trace event and flips the tracepoint strings passed
to it
At the end of the renaming exercise, the remaining RCU references to "dyntick"
are:
- Comments in core RCU code:
kernel/rcu/:
tree.c:354:56: * We inform the RCU core by emulating a zero-duration dyntick-idle period.
tree.c:769:10: * is in dynticks idle mode, which is an extended quiescent state.
tree.c:784:54: * by virtue of being in or having passed through an dynticks idle state since
tree.c:799:44: * If the CPU passed through or entered a dynticks idle phase with
tree.c:1983:14: /* Collect dyntick-idle snapshots. */
tree.c:1986:13: /* Handle dyntick-idle and offline CPUs. */
tree.c:2680:54: * Otherwise, invoke the specified function to check dyntick state for
tree.c:2740:16: * CPUs are in dyntick-idle mode.
tree_plugin.h:863:4: * dyntick-idle quiescent state visible to other CPUs, which will in
tree_nocb.h:55:19: * about entering dyntick-idle mode.
tree.h:208:8: /* 3) dynticks interface. */
tree.h:209:46: int watching_snap; /* Per-GP tracking for dynticks. */
Kconfig:11:4: # Dynticks-idle tracking
- Stale documentation in RCU/Design/Data-Structures/Data-Structures.rst
referencing fields that have been moved out of RCU after
904e600e60f4 ("rcu/context_tracking: Move dynticks_nesting to context tracking")
The series is based on rcu/next at:
b93b7b4635f1 ("ftrace: Asynchronous grace period for register_ftrace_direct()")
It's also available as a git tree at:
https://gitlab.com/vschneid/linux.git -b redhat/isolirq/defer/v3-rcu-v2
Cheers,
Valentin
